Database Concepts

Data is the fuel that powers machine learning. The more of it you have, the better your models tend to perform. But real-world data comes with a lot of baggage. Privacy concerns, legal restrictions, high collection costs, and sometimes, just plain scarcity. Synthetic data is how the industry is working around that problem.

Simply put, synthetic data is artificially generated data that mimics real data without actually being real.

It’s not collected from users, scraped from the web, or pulled from production systems. It’s created by algorithms, statistical models, or AI systems that have learned the patterns and structure of real data well enough to produce convincing imitations of it.

As AI has become central to how software is built, the database industry has responded in two ways. Some databases have added AI features on top of their existing architecture. Vector search here, a natural language query interface there. Others have been built from scratch with AI workloads as the primary design constraint.

That second category is what we mean by “AI-native”.

Databases are everywhere. Every app you use, every website you visit, every transaction you make is backed by a database. But keeping a database running well has always required a lot of human expertise. Expertise for things like tuning performance, managing storage, applying patches, backing up data, scaling up when traffic spikes. For decades, this was just the cost of doing business. You hired database administrators, and they kept the lights on.

A self-driving database is one that handles most of that work itself.

High-dimensional vector search is a foundational way AI systems find similar or relevant items across large datasets when the data has been converted into vectors. If you’ve used semantic search, gotten eerily accurate recommendations, or worked with a retrieval-augmented AI tool, this is often the mechanism running underneath.

Semantic retrieval is a way of finding information based on meaning rather than matching exact words. You ask a question or describe what you need, and the system finds relevant results even if they use completely different wording. That gap between what someone types and what they actually mean is exactly what semantic retrieval is designed to close.

One of the hardest things about building AI systems is that the things humans care about (words, sentences, images, ideas, etc) aren’t naturally something a computer can do math on. A computer doesn’t inherently know that “happy” and “joyful” are similar, or that a photo of a dog and the word “dog” are related. It just sees raw data.

Embeddings are the solution to that problem.
